Woodworking while camping-the next iteration

We camp in primitive Forest Service campgrounds more than 30 days a year and I really enjoy woodworking outside in such beautiful locations.  There's always a heavy, rugged picnic table in the site and I take advantage of it by clamping a bench raiser to the top and laying out my tools on the seat.  I went through several iterations before I settled on what worked for me.

I made a nice portable tool chest but it has proven to be unsatisfactory.  It is heavy and awkward to get out  and put away every day in the confined space where I store it, it slides around on the move and it takes up a lot of space.  I decided to come up with something different.  Scratching my head, I noticed something about my "bench:"

When it's turned over, there are two compartments that are about a foot square each.  I decided to make two boxes that would fit in them so they would be secured in transit and conserve space.  Dividing the tools up would make the boxes easier to handle and, as often happens, I came up with a crazy idea.  What if I made the tops of the boxes a shooting board and a bench hook?  I have been carrying them anyway so this would let them do double duty and save space.  Here's what I came up with:

Each box contains a top tray...

and space for larger tools in the bottom:

They aren't big enough for saws, so I made a separate till for them:

Everything together is quite compact:

I consider this what auto designers call a development mule and, with 20/20 hindsight would do some things differently but they seem like a step forward and I look forward to getting some experience with them.
